Comparison of mass and weight on Earth and the Moon.

Problem Analysis:

The worksheet focuses on the concepts of mass and weight, explaining how they differ. Key points from the text are:
1. Mass is the total amount of matter in an object and does not change unless matter is added or removed.
2. Weight is the force of gravity acting on an object's mass and can change depending on the strength of gravity.
3. The Moon's gravity is weaker than Earth's, so an object weighs less on the Moon compared to Earth.

Questions and Solutions:

Let’s analyze each question step by step:

---

#### Question 1:
"On Earth, the astronaut's weight is ____________ her weight on the Moon."

- Explanation: Weight depends on the gravitational force. Since the Moon's gravity is weaker than Earth's, the astronaut will weigh less on the Moon than on Earth.
- Answer: greater than

---

#### Question 2:
"On the Moon, the astronaut's mass is ____________ her weight on Earth."

- Explanation: Mass is the amount of matter in an object and does not change with location. However, weight changes with gravity. The question asks about mass compared to weight on Earth. Since mass is constant and weight on Earth is greater due to stronger gravity, the astronaut's mass is less than her weight on Earth (in terms of numerical value).
- Answer: less than

#### Question 3:
"The astronaut's volume on Earth is ____________ her volume on the Moon."

- Explanation: Volume is the amount of space an object occupies. It does not change with location because it is a property of the object itself, not influenced by gravity.
- Answer: the same as

---

#### Question 4:
"The astronaut has ____________ amount of matter on the Earth and on the Moon."

- Explanation: Mass is the measure of the amount of matter in an object. Since mass does not change with location, the astronaut has the same amount of matter on both Earth and the Moon.
- Answer: the same

---

#### Question 5:
"The astronaut ____________ made of matter."

- Explanation: All objects, including astronauts, are composed of matter. This is a fundamental property of physical objects.
- Answer: is
